Hairy vetch is a hard-working, fast-growing cover crop, adding large amounts of nitrogen into the soil. It grows quickly and densely, helping to prevent pesky weeds. At the bloom stage, it contributes the most nitrogen and is easiest to incorporate. It biodegrades quickly, needing just a few weeks of rest before sowing your next crop. Usually winter hardy in USDA zones 4 and warmer, resuming growth the following spring. While top growth may be slow in the winter, it acts as a blanket to your soil, preventing erosion from wind or water and the deep roots are still growing, feeding soil organisms, and improving soil structure and water retention. Fairly drought tolerant and also tolerant of temporary flooding. Plants grow up to 24″ tall and can reach up to 12″ long. Botanical Interests’® Hairy Vetch Cover Crop Seeds are USDA Organic and have been verified by The Non-GMO Project.

What is an heirloom seed?
An heirloom variety is one that has been passed down from generation to generation. Generally, the variety must have been around for at least 50 years. They are open-pollinated, which means they have been exposed to natural pollination methods like insects or winds. They aren’t hybrids or genetically modified.
